The major indices continued to rally into the close Monday, after spending most of the day down substantially. The Dow ended the day up fractionally and the S&P 500 was down less than one point. Institutional money continues to enter the markets, says Jim Cramer, and that has limited the size and duration of pullbacks.

Even as the uncertainty comes out of the markets, the clarity that replaces it is tepid at best. But with the S&P 500 resting at seven-month highs, one troublesome sector has badly lagged: housing and home-building stocks.
